Several organizations have been creating visualizations for historic climatic changes using GIFs. These visualizations are engaging and convey a complex message simply. They can also be useful for helping people explain historic changes succinctly. As “animated GIFs,” these visualizations are relatively small files that can be downloaded and used in a PowerPoint presentation even without an Internet connection.

Check out this GIF published through a BBC news story visualizing global temperature increases from 1850 to 2016: http://www.climate-lab-book.ac.uk/files/2016/09/spiral_aug2016.gif
